Single API for multi-model orchestration
Fugu routes requests through a coordinated pool of specialized models, handling model selection and switching for each task through one API.
Sakana Fugu
Sakana Fugu is a multi-agent model API that routes tasks across specialized models through one OpenAI-compatible endpoint. It is positioned for coding, reasoning, and other quality-critical workflows, with configurable agent selection and no public pricing shown in the provided sources.
Overview
Sakana Fugu is a multi-agent system delivered as a single model API. It dynamically coordinates a pool of specialized models to handle multi-step tasks, rather than relying on a fixed human-designed workflow.
The page positions Fugu for coding, reasoning, and other quality-critical work. It offers two models, Fugu and Fugu Ultra, both available through an OpenAI-compatible API, so teams can choose a lower-latency default or a deeper orchestration setup for harder problems.
Sakana also says users can control which agents are allowed into the pool, which makes the product relevant when data handling, privacy, compliance, or internal policy requirements affect model choice. The site notes that Fugu is not yet available in the EU/EEA while compliance work is in progress.
Key capabilities
Built for complex tasks
The system is designed for coding, reasoning, and other quality-sensitive workflows where coordination across agents can improve result quality.
Configurable agent selection
Users can exclude specific providers or models from the pool to match data, privacy, compliance, or organizational requirements.
Two model variants
The product offers both Fugu and Fugu Ultra, letting users choose a default option with lower latency or a deeper pool optimized for harder problems.
OpenAI-compatible API
Fugu is available through an OpenAI-compatible API, which supports integration without changing the overall interface pattern.
Research-backed orchestration
The research section explains that the system is grounded in the TRINITY and Conductor papers on learned model orchestration.
Practical use cases
General multi-agent API layer
Use Fugu as the default model layer when you want a single endpoint to route work across different specialists without building custom orchestration logic yourself.
Coding and code review
Apply Fugu to coding and code review workflows where the site says it can support quality-critical tasks with strong performance and low latency.
Hard reasoning and research tasks
Use Fugu Ultra for difficult, high-stakes problems where the page says it coordinates a deeper pool of expert agents for higher answer quality.
Policy-constrained deployments
Choose Fugu when your organization needs to exclude specific providers or models to satisfy data handling, privacy, compliance, or policy requirements.
Specialized analysis workflows
Use the product in workflows such as chatbot services, Kaggle competitions, paper reproduction, cybersecurity analysis, and literature or patent investigations, which are explicitly named on the site.
Pros and Cons
Pros
- Coordinates multiple specialized models through one API, reducing the need to manage orchestration logic yourself.
- Supports tasks where answer quality matters, including coding and reasoning workflows.
- Allows specific agents or providers to be excluded for policy, privacy, or compliance reasons.
- Provides two model options, including a lower-latency default and a higher-capacity option for harder tasks.
- Uses an OpenAI-compatible API, which lowers the friction of integration for existing users.
Cons
- The pricing page in the collected sources returns a 404, so public pricing and plan details are not available in the provided evidence.
- The product is not yet available in the EU/EEA according to the site.
- The page gives fewer implementation details than a full documentation set, so setup and operational limits are not fully specified in the source.
